Hi there! For open-world environments in UE5, here are a few optimization tips:
- Use Lumen for real-time dynamic lighting without baking.
- Limit the number of dynamic light sources in your scene.
- Enable Distance Field Ambient Occlusion (DFAO) for distant shadowing.
- Split your world into World Partition levels to stream only necessary areas.
- Optimize Lightmap Resolution for static meshes.
Hope this helps your project run smoother!
